8 - 4 = 7 - 3 because it has a equal sign in the middle meaning that you have to find an equation that’s equal to it. So thats why the missing number is 3
Answer:
Step-by-step explanation:in standard form y= ax+b
-4y = -3x+28
4y =3x-28
or y= 3/4 x -7
So a= 3/4 = slope and -7 is y intercept ( parallel lines have same slope)
Equation 3 is
y= 3/4x-2
which also has slope = 3/4 and y intercept = -2
Parallel lines have same slope
Similarly a perpendicular line will have slope of - 1/a
For equation
y= ax+b
Perpendicular line is
y=( -1/a) x +c
Answer:
In order to find the slope, we would need to format the coordinates like rise over run (y/x)
We find two points, (-6, 12) and (-5, 14)
Now we subtract the y coordinates from each other and do the same for the x coordinates
14 and 12 are our y coordinates so that will be our rise
-5 and -6 are x coordinates so that will be our run
14 - 12 2
_______ = ______
-5 - (-6) 1
2 is the slope
